057 AXPZ20 KNHC 260903 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sat Jul 26 2025 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...TROPICAL WAVES... A tropical wave axis is analyzed along 109W from 02N to 16N, moving westward around 10-15 kt. Scattered moderate convection is from 06N to 13N between 106W to 115W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 09N127W to 13N140W. Scattered moderate convection prevails within 200 nm on either side of the monsoon trough and E of 102W, and from 03N to 18N W of 122W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A surface trough extends from 32N113W to 26N110W, then a surface ridge dominates the remainder of the area. Fresh to strong N to NW winds and moderate seas prevail offshore of Baja as a result of the pressure gradient between these two features. Moderate to fresh N to NE winds prevail in the Gulf of Tehuantepec. Gentle or weaker winds prevail over the rest of the waters. Seas are mainly moderate in SW swell, with slight seas in the Gulf of California. For the forecast, fresh to strong NW winds will continue offshore of Baja California north of Cabo San Lazaro through the weekend as the pressure gradient builds between troughing over the Gulf of California and high pressure to the west. Pulsing fresh to strong gap winds in the Gulf of Tehuantepec will increase to strong to near-gale force Sun night through early next week as high pressure builds southward through Mexico. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE winds are occurring in the Gulf of Papagayo as low pressure prevails over northwestern Colombia. Elsewhere, scattered showers and thunderstorms are offshore of Panama, with gusty winds and building seas likely near convection. Moderate SW winds prevail south of the monsoon trough. Moderate seas in SW swell are noted through the regional waters. For the forecast, fresh NE to E winds will continue to pulse in the Gulf of Papagayo into next week as low pressure prevails in the south-central Caribbean. Moderate to fresh SW winds will continue south of the monsoon trough through the weekend, then diminish slightly. Moderate seas in SW swell are expected across the Central and South American waters into next week. ...REMAINDER OF THE AREA... Surface ridging extends through much of the waters north of the monsoon trough. Light to gentle winds are noted north of 25N and west of 125W. Farther south, moderate to fresh NE winds and rough seas from 10N to 20N west of 120W. Moderate to fresh SE winds are occurring south of the monsoon trough. Seas are generally moderate. For the forecast, moderate to fresh N to NE winds will prevail north of the monsoon trough to 25N, expanding farther north through the weekend as high pressure strengthens north of the area. Rough seas generated by fresh winds will occur from 10N to 15N west of 130W though Sun, then rough seas may develop south of the monsoon trough on Sun night through early next week. $$ ERA
